Abstract: In the present disclosure, an access point obtains a current network feature and generates a matching rule and an access rule, so that a station performs uplink access according to the matching rule and the access rule. This resolves a prior-art problem of reduced quality of service of a high-priority service because in an EDCA protocol, when there are relatively many low-priority service nodes, the high-priority service has difficulty in obtaining a resource through contention, or a conflict occurs between a low-priority packet and a high-priority packet. Effects of ensuring quality of service and user experience are achieved.

Abstract: Embodiments of this application disclose a spatial reuse indication method and a wireless communications apparatus, thereby reducing a quantity of nodes that can participate in spatial reuse, reducing mutual interference between nodes in spatial reuse, and improving spatial reuse system performance. The method in some implementations includes a first access point generates a spatial reuse limitation indication and a spatial reuse group indication. The spatial reuse limitation indication can be used to indicate whether only a node in a spatial reuse group is allowed for spatial reuse and to indicate the spatial reuse group. The spatial reuse group includes one or more basic service sets. The first access point sends the spatial reuse limitation indication and the spatial reuse group indication.
